Answer:
They were very superstitious.
Explanation:
Many of the superstitions that people still have today originated from the Middle Ages. Those who lived during that time didn't know everything about the world yet. Examples of these superstitions are the fear of the number 13, the fear of getting seven years of bad luck after breaking a mirror and even the lucky horseshoe.
If we are talking early early then it was because art wasn't a form of "art" it was a form of communication.
But a little later down the road, people did not understand the human body and could not paint one perfectly, and also painters loved to show perfection, as in, gold everywhere, or a kind a top a thousand bodies. Something like that. So yeah...
